  • Beschreibung: <p> We obtain Gaussian upper and lower bounds on the transition density q<sub>t</sub>(x,y) of the continuous time simple random walk on a supercritical percolation cluster C<sub>∞</sub>in the Euclidean lattice. The bounds, analogous to Aronsen's bounds for uniformly elliptic divergence form diffusions, hold with constants c<sub>i</sub>depending only on p (the percolation probability) and d. The irregular nature of the medium means that the bound for q<sub>t</sub>(x,·) holds only for t≥ S<sub>x</sub>(ω), where the constant S<sub>x</sub>(ω) depends on the percolation configuration ω. </p>
